| 摘要： |
| 通过对茶梁子矿区的地质背景、矿体特征、矿石特征及岩石地球化学特征进行综合研究，初步探讨了矿床的成因。认为矿体是由含硫质的低温热液携带矿质运移到断裂构造的有利部位沉淀而形成的。同时在表生环境下，原生矿体经过后期的次生改造作用后，形成了富含铁、锰氧化物的土状矿石，并且以较为富集的铁、锰氧化物作为寻找钴的直接标志 |

| Abstract: |
| Based on analyses of geological background, ore body features and petro-geochemistry features, the authors preliminary discussed the genesis of ore deposits in Chaliangzi ore district. The formation of ore bodies were related to sulfur-rich epithermal fluid. The fluid carried minerals and transported to the vantage point of fault zone, and then the minerals were deposited. In the superficial environment, primary ore body change into earthy ore that was rich in iron manganese oxide by secondary reformation.The rich iron manganese oxide could be the indicators for exploring cobalt ore. |
